About This Game

Brace yourself for a relentless alien assault in Let Them Come: Onslaught, where bullet heaven gameplay collides with the gritty spirit of retro sci-fi classics.

Each run challenges you to create the perfect build from an arsenal of over-the-top weapons and explosive upgrades—shredding alien hordes in a display of retro-fueled chaos. If you’re seeking a survivors-like experience with a vintage action movie vibe, set to the pulsing beat of a soundtrack by Cartridge 87, this game sets itself apart from the pack.

MULTIPLE WEAPON UNLOCKS

Unleash your inner action hero with weapons straight out of your favorite sci-fi flick, from flamethrowers to Photon Sabers and more. You can even nuke the site from orbit - it’s the only way to be sure. Each weapon brings a distinct playstyle, and upgrades let you stack up devastating combos. Whether you prefer crowd-clearing firepower, targeted precision, or life-saving shields, you can tailor your loadout for maximum carnage (and maximum style).

DEEP REPLAYABILITY

No two runs are ever the same. Between battles, invest your hard-earned rewards to unlock and enhance new skills, refine your strategy, and push deeper into enemy territory. Experimentation is key—try different weapon synergies, combine special effects, and perfect your approach until your unstoppable build leaves nothing but alien rubble in its wake.

You won’t just fight endless waves, you’ll revel in them. As the alien onslaught intensifies, your reflexes and tactics are put to the test. Survive long enough, and you’ll face towering bosses that demand every ounce of skill you’ve honed. It’s the ultimate showdown, straight from the adrenaline-drenched heyday of retro sci-fi action. Gear up, lock ‘n load, and get ready to Let Them Come, because the Onslaught is about to begin!

AN ALL ORIGINAL SOUNDTRACK

Every beat fuels the action, whether you’re dodging, blasting, or barely holding the line, the music pushes you deeper into the chaos. Feel the pulse of battle with a synth-driven soundtrack by Cartridge 87, designed to keep your adrenaline pumping as the alien horde closes in.
